引言

上一篇讲到了ReentrantLock,在同一个时间点,只能用一个线程能够访问共享资源.今天我们来讲一下读写锁ReadWriteLock,读写锁提供了在同一个时间点,可以有多个线程共享去读取共享资源,当只有有一个线程去写共享资源.

ReadWriteLock主要是Lock锁使用的,提供一个读和一个写的操作.readLock可以在有多个线程同时操作直到没有写的操作.writeLock却在同一个时间点只能有一个线程在操作.

所有ReadWriteLock的实现类必须在writeLock写操作时,保证内存同步,同时还必须和readLock相关联,比如当一个线程获取到读锁时,这必须保证当前线程能在写锁释放后看到所有的更新操作.

例子

首先定一个模拟读写文件的类MockFIle

public class MockFile {    // 使用StringBuilder而不是使用StringBuffer    // 是因为StringBuilder是线程不安全的,而StringBuffer是线程安全的    StringBuilder fileContent;    public MockFile() {        this.fileContent = new StringBuilder();    }    public String readFile(){        try {            Thread.sleep(10);            String content = fileContent.toString();            Thread.sleep(10);            return content;        } catch (InterruptedException e) {            return null;        }    }    public void writeFile(char content){        try {            Thread.sleep(10);            fileContent.append(content);            Thread.sleep(10);        } catch (InterruptedException e) {            e.printStackTrace();        }    }}

注意在该类使用StringBuilder是因为这个类是线程不安全的
StringBuffer是线程安全的

之后编写读文件操作 ReadRunnable

public class ReadRunnable implements Runnable {    ReadWriteLock lock;    MockFile file;    boolean isStop;    public ReadRunnable(ReadWriteLock lock, MockFile file) {        this.lock = lock;        this.file = file;        isStop = false;    }    @Override    public void run() {        Thread self = Thread.currentThread();        while(!isStop){            Lock lock = this.lock.readLock();            try {                lock.lock();                String content = file.readFile();                System.out.println(self.getName() + " read: " + content);                Thread.sleep(10);            } catch (InterruptedException e) {                e.printStackTrace();            }finally {                lock.unlock();                try {                    Thread.sleep(50);                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }    }    public void setStop() {        isStop = true;    }}

然后再编写写文件操作 WriteRunnable

public class WriteRunnable implements Runnable {    ReadWriteLock lock;    MockFile file;    String content;    public WriteRunnable(ReadWriteLock lock, MockFile file, String content) {        this.lock = lock;        this.file = file;        this.content = content;    }    @Override    public void run() {        Thread self = Thread.currentThread();        for (char ch : content.toCharArray()){            Lock lock = this.lock.writeLock();            try {                lock.lock();                System.out.println(self.getName() + " write " + ch);                file.writeFile(ch);                Thread.sleep(20);            } catch (InterruptedException e) {                e.printStackTrace();            } finally {                lock.unlock();                try {                    Thread.sleep(200);                } catch (InterruptedException e) {                    e.printStackTrace();                }            }        }    }}

这里需要注意以下几点

读文件操作比写文件操作频繁,这样才能看到边写边读的效果,这就需要在释放锁的时候,让写线程睡久一点,让读线程睡少一点

还有我这里采用判断标记位的方式,让读线程停止操作

最后,我们需要写一个测试类 TestMain

public class TestMain {    public static void main(String[] args) {        MockFile mockFile = new MockFile();        ReentrantReadWriteLock lock = new ReentrantReadWriteLock();        Thread thread1 = new Thread(new WriteRunnable(lock, mockFile, "ABCDEFGHIJKLMOOPQRSTUVWXYZ"));        Thread thread2 = new Thread(new WriteRunnable(lock, mockFile, "abcdefghijklmoopqrstuvwxyz"));        Thread thread3 = new Thread(new WriteRunnable(lock, mockFile, "0123456789"));        List
    
      readThreadList = new ArrayList<>();        List
     
       readRunnables = new ArrayList<>();        for (int i = 0; i < 5; i ++){            ReadRunnable readRunnable = new ReadRunnable(lock, mockFile);            readThreadList.add(new Thread(readRunnable));            readRunnables.add(readRunnable);        }        thread1.start();        thread2.start();        thread3.start();        for (Thread readThread : readThreadList){            readThread.start();        }        while (thread1.isAlive() || thread2.isAlive() || thread3.isAlive());        for (ReadRunnable readRunnable : readRunnables){            readRunnable.setStop();        }    }}

测试类,需要注意以下几点

创建了三个写操作,
+ 第一个依次写入26个大写字母+ 第二个依次写入26个小写字母+ 弟三个依次写入0-9十个数字
创建了五个读操作,让它们不断的读取文件

当全部写操作结束时,这停止这五个读操作

运行程序,结果如下
